Getting 99 Sierra Classic back to stock height

[Sox8999]

Good Evening, 

 

I inherited a 99 GMC Sierra Classic from my FIL and it's currently lowered. I'm a noob to truck suspension so I'll attach some pics. Can you let me know what it looks like they did to it and how I can get it back to stock? Thanks!

Going to need new front springs and a set of factory shackles and you will be back to stock.

Carnau, 

Thanks so much for the response! So I don't need to get stock spindles? That's what I was suggested to do, but it didn't look like they used a lowering spindle?

From the above pictures is doesn't look like a lowering spindle was used.

Just looks like the spring was cut or a shorter spring was used.
